## VSCode
### 下載新版本JDK

## Debug相關
除錯所噴的錯無論是否有影響程式執行都放在這
### Flutter Build Error: Process 'command 'E:\Flutter Apps\flutter\bin\flutter.bat'' finished with non-zero exit value 1


flutter clean

### Note: Some input files use or override a deprecated API.Note: Recompile with -Xlint:deprecation for details.

### Waiting for another flutter command to release the startup lock...

執行以下:

taskkill /F /IM dart.exe

### [FlutterDaemon] [Error] Checking Dart SDK version... �o�ӮɭԤ����� <<�C

此問題為誤推flutter的commit導致
還好提示訊息說會有衝突
捨棄衝突

git merge --abort

就可以正常使用Dart進行編譯了

## adb相關
### adb.exe: more than one device/emulator
1. 檢查是不是有多個模擬器

    adb devices


2. 假設有一個以上的模擬器就需要對adb指令給予對應的機器序列號 -s

    adb -s emulator-5554 shell

### Activity not started, unable to resolve Intent
此錯誤可以忽略它只是告訴你APP正在運作
## 輸出Release APK相關

### Build failed with an exception. Execution failed for task ':app:validateSigningRelease'.
執行

flutter build apk

此錯誤發生原因為`/android/key.properties`的文件，storeFile的路徑斜線打反了導致改為使用`/`即可:

storePassword=剛剛輸入的密碼
keyPassword=剛剛輸入的密碼
keyAlias=key
storeFile=輸入本地金鑰儲存位置，例如: C:/dev/flutter/key/key_test.jks >> 這邊

## 模擬器相關
### INSTALL_FAILED_INSUFFICIENT_STORAGE

解法：
此為手機模擬器內存空間不足導致，調整模擬器內存大小

## Mac
### Error running pod install
